In statistical analysis, distributional assumptions are needed to apply parametric procedures. Assumptions about underlying distribution should be true for accurate statistical inferences. Goodness-of-fit tests are used for checking the validity of the distributional assumptions. To apply some of the goodness-of-fit tests, the unknown population parameters are estimated. The null distributions of test statistics become complicated or depend on the unknown parameters if population parameters are replaced by their estimators. This will restrict the use of the test. Goodness-of-fit statistics which are invariant to parameters can be used if the distribution under null hypothesis is a location-scale distribution. For location and scale invariant goodness-of-fit tests, there is no need to estimate the unknown population parameters. However, approximations are used in some of those tests. Different types of estimation and approximation techniques are used in this study to compute goodness-of-fit statistics for complete and censored samples from univariate distributions as well as complete samples from bivariate normal distribution. Simulated power properties of the goodness-of-fit tests against a broad range of skew and symmetric alternative distributions are examined to identify the estimation effects in goodness-of-fit tests. The main aim of this thesis is to modify goodness-of-fit tests by using different estimators or approximation techniques, and finally see the effect of estimation on the power of these tests.

The research on person-organization fit has attracted the attention of both scholars and managers in recent years. During organizational transformation, it is very important to have employees who can identify with the administration of the company and struggle for the company's future. This will enable the company to keep competitiveness and flexibility to confront environmental challenges. In this paper, Taiwan Salt Industrial Corporation (TSIC) is chosen as the subject for case study and several methods were used; including stratified sampling method and interviews with top manager. The value construct technique modified by Cable & Judge combined with template-matching technique by Bem & Allen were adopted to study person-organization fit in the company. Then, by statistical methods, the influences of person-organization fit on organization commitment and organization citizenship behavior were predicted. The major empirical findings of this study are as follows: 1. There are differences between the ideal culture values that employees wish for and those they really perceive. 2. Person-organization fit is related to employee's demography. 3. It is significantly positive trend to predict intent to remain, organization commitment and its factor, organization recognition, of employees by their person-organization fit 4. Organization citizenship behavior of employees is less significant related to their person-organization fit. 5. The age and tenure of employees has a significantly positive relationship with organization commitment and its factor, organization recognition; however, education level of employees has a negative one with organization recognition.

This paper proposed a revised technology acceptance model for measuring end user computing (EUC) acceptance. An empirical study was conducted to collect data and the revised model was evaluated by structural equation modeling, and then confirmatory factor analysis was applied to test if the empirical data confirmed to the presumed model. The results demonstrated that the model explained 56% of the variance. The finding contributes to an expanded understanding of the factors that promote the EUC acceptance.

Most of previous works focused on the relationship between organizational attractiveness as an employer and instrumental attributes of employer image. Potential job seekers were viewed as rational and alone decision makers. However, in addition to objective facts, potential job seekers consider other facts when they make a job decision such as emotional facts and perceived harmony with organization. Furthermore, potential job seekers hold a vague impression on a potential employer. Others¡¦ opinions of potential employers must be their crucial information sources and they may change decision because of others¡¦ opinion. The study add symbolic meaning construct to employer image and research the relationship between it and organizational attractiveness as an employer and found it is significant related to organizational attractiveness as an employer. The mediated effect of the similarity between potential job seekers¡¦ personality and organizations¡¦ personality and others¡¦ opinions are considered here. Both of them don¡¦t significant mediated the relationship between employer image and organizational attractiveness as an employer.

Curved and skewed I-girder bridges exhibit torsional displacements of the individual girders and of the overall bridge cross-section under dead loads. As a result, the girder webs can be plumb in only one configuration. If the structure is built such that the webs are plumb in the ideal no-load position, they generally cannot be plumb under the action of the structure's steel or total dead load; hence, twisting of the girders is unavoidable under dead loads. The deflected geometry resulting from these torsional displacements can impact the fit-up of the members, the erection requirements (crane positions and capacities, the number of temporary supports, tie down requirements, etc.), the bearing cost and type, and the overall strength of the structure. Furthermore, significant layover may be visually objectionable, particularly at piers and abutments. If the torsional deflections are large enough, then the cross-frames are typically detailed to compensate for them, either partially or fully. As specified in Article C6.7.2 of the AASHTO LRFD Specifications, different types of cross-frame detailing methods are used to achieve theoretically plumb webs under the no-load, steel dead load, or total dead load conditions. Each of the cross-frame detailing methods has ramifications on the behavior and constructability of a bridge. Currently, there is much confusion and divergence of opinion in the bridge industry regarding the stage at which steel I girder webs should be ideally plumb and the consequences of out-of-plumbness at other stages. Furthermore, concerns are often raised about potential fit-up problems during steel erection as well as the control of the final deck geometry (e.g., cross-slopes and joint alignment). These influences and ramifications of cross-frame detailing need to be investigated and explained so that resulting field problems leading to needless construction delays and legal claims can be avoided. This dissertation addresses the influence of cross-frame detailing on curved and/or skewed steel I girder bridges during steel erection and concrete deck placement by conducting comprehensive analytical studies. Procedures to determine the lack-of-fit forces due to dead load fit (DLF) detailing are developed to assess the impact of different types of cross-frame detailing. The studies include benchmarking of refined analytical models against selected full scale experimental tests and field measurements. These analytical models are then utilized to study a variety of practical combinations and permutations of bridge parameters pertaining to horizontal curvature and skew effects. This research develops and clarifies procedures and provides new knowledge with respect to the impact of cross-frame detailing methods on: 1) constructed bridge geometries, 2) cross-frame forces, 3) girder stresses, 4) system strengths, 5) potential uplift at bearings, and 6) fit-up during erection. These developments provide the basis for the development of refined guidelines for: 1) practices to alleviate fit-up difficulties during erection, 2) selection of cross-frame detailing methods as a function of I-girder bridge geometry characteristics, and 3) procedures to calculate the locked-in forces due to DLF cross-frame detailing.

<p>Humanitarian logistics is a young science and complex discipline compared to business logistics because not only are actors in that arena compelled to work with outmost speed in <em>interrupted </em>environments having undetermined demand, they are also forced to work closely with other unknown players. Even more complex are civil-military relations because as studies show, the differences between these two humanitarian actors run deep to include contrasting missions, humanitarian principles, organizational and cultural differences.</p><p>The purpose of this work is to examine civil-military relations during the preparedness and response phases of humanitarian crises. We developed a frame of reference, set forth some operational and theoretical definitions, examined overlapping supply chains, modeled organizational structures and coordination mechanisms, established civil-military cooperation framework, disaster cycle studies and proposed a working model.</p><p>Our methodology included primary data collection through an empirical study of two NGOs and the military force through a series of interviews. Data culled was then analyzed in conjunction with the models and literature outlined in the frame of reference.</p><p>Based on our analysis, a number of observations were made in the conclusion. To begin with a number of strategies are employed during the preparedness and response phase where speed and agility are crucial. Also, overlapping roles between the military and NGOs have both positive and negative impact. Different organizational structures and funding outlay mean differences abound in how actors coordinate activities and share information. Cooperation, trust, information sharing and coordination are closely linked when finding a strategic fit among actors. In spite of the attempt at seeking a right formula for civil-military relations, it would be erroneous to ‘standardize’ relations as no two cases are ever the same.</p>

Yet despite the long history of science, the extent to which theories are supported or contradicted by the results of empirical research remains ill defined. Quite commonly, support or contradiction is based solely on the "reject" or "fail to reject" decisions that result from tests of null hypotheses that are derived from aspects of theory. Decisions and recommendations based on this forced and often artificial dichotomy have been scrutinized in the past. Such an overly simplified approach to theory testing has been vigorously challenged in the past. Theories differ in the extent to which they provide precise predictions about observations. The precision of predictions derived from theories is proportional to the strength of support that may be provided by empirical evidence congruent with the prediction. / ABSTRACT: However, the notion of precision linked to strength of support is surprisingly absent from many discussions regarding the appraisal of theories. In the early 1990s, Meehl presented an index of corroboration to summarize the extent to which empirical tests of theories provide support or contradiction of theories. This index is comprised of a closeness component and an estimate of precision. The purpose of this study was to evaluate the utility of this index of corroboration and its behavior when employing path analytic methods in the context of social science research. The performance of a multivariate extension of Meehl's Corroboration Index (Ci) was evaluated using Monte Carlo methods by simulating traditional path analysis. Five factors were included in the study: model complexity, level of intolerance, verisimilitude, sample size and level of collinearity. Results were evaluated in terms of the mean and standard error of the resulting multivariate Ci values. / ABSTRACT: Of the five central design factors investigated, the level of intolerance was observed to be the strongest influence on mean Ci. Verisimilitude and model complexity were not observed to be strong determinants of the mean Ci. The lack of sensitivity of the index to the other design factors led to a proposed alternative conceptualization of the multivariate corroboration index to guide future research efforts. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Results indicated that factor pattern fit between the female samples on the common model was good-to-mediocre, and factor pattern fit between the male samples and the common model was mediocre-to-poor. Both samples exhibited significant changes in chi square when testing for the more restrictive factor loading equivalence. Partial measurement invariance revealed a better fit between the male samples when three of the items were unconstrained, and when eight items were unconstrained between the female samples. Finally, males and females in the ANZ sample exhibited factor pattern invariance, but required two items to be unconstrained before factor loading invariance was achieved. / ABSTRACT: Mean differences on the six scales revealed higher levels of time-based work interference with family and family interference with work for males than for females in the ANZ sample. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

This study investigated the efficacy of the lz person fit statistic for detecting aberrant responding with unidimensional pairwise preference (UPP) measures, constructed and scored based on the Zinnes-Griggs (ZG, 1974) IRT model, which has been used for a variety of recent noncognitive testing applications. Because UPP measures are used to collect both "self-" and "other-" reports, I explored the capability of lz to detect two of the most common and potentially detrimental response sets, namely fake good and random responding. The effectiveness of lz was studied using empirical and theoretical critical values for classification, along with test length, test information, the type of statement parameters, and the percentage of items answered aberrantly (20%, 50%, 100%). We found that lz was ineffective in detecting fake good responding, with power approaching zero in the 100% aberrance conditions. However, lz was highly effective in detecting random responding, with power approaching 1.0 in long-test, high information conditions, and there was no diminution in efficacy when using marginal maximum likelihood estimates of statement parameters in place of the true values. Although using empirical critical values for classification provided slightly higher power and more accurate Type I error rates, theoretical critical values, corresponding to a standard normal distribution, provided nearly as good results.

Authors: Niklas Hansson and Niklas Johansson Supervisor: Svante Andersson Keyword(s): Sponsorship, Sport sponsorship, Sponsorship fit, Sponsorship objectives, Sponsorship outcomes, Sponsorship approach Purpose: The purpose of this study is to describe and explore how companies and sports teams decide to enter sponsorship agreements with each other. The purpose is also to explore the entire sponsorship process together with the specific relationships between sponsor/-s and sponsee/-s. This will be done in order to make a contribution to the research field of sponsorship in the context of sports teams. Research Problem: How does the sponsorship process form and how do sponsors/ sponseeswork with their sponsorship relationships? Method: The main methodological choice has been the abductive research method, where theories have been added and removed from the framework, in order to analyse data properly. A qualitative approach has been chosen and empirical data from eight organisations form two cases with three sponsors and one sponsee has been gathered. Primary data were collected from personal interviews and complemented with secondary data from websites and other material provided by the respondents. Theoretical Framework: The theoretical framework consists of classic sponsorship theories,in order to form a solid theoretical base for the concept of sponsorship. These classics are presented together with more modern theories regarding sponsorship in connection to certain aspects of the process and relationships and thus making the theoretical framework current and up to date. Conclusion: The process has been seen to take one out of two options, whereas a structured sponsorship process is one option and the other option is a rather unstructured sponsorship process. Sponsors and sponsees reported that they work increasingly with their networks and thus suggested that the network approach connected to sponsorship will grow more important in the upcoming years. Generally, it appears as if the main focus within sponsorship, in terms of fit, is how it works internally or within the agreement between sponsor and sponsee. Whether it signals something good or bad to the audience is therefore of no real interest or matter.
